政府财政干预门槛、异质性FDI与区域创新能力

外商直接投资（FDI）是东道国实现技术创新的重要途径。创新行为导致的市场失灵为政府对创新活动进行干预提供了理论上的支撑。本文利用2001—2015年中国省级面板数据，分别从资源导向型FDI、效率导向型FDI和市场导向型FDI三种类型探讨异质性FDI对区域创新能力的影响，并将政府财政干预纳入研究框架中，深入研究异质性FDI对区域创新能力影响的政府财政干预门槛效应。结论表明：异质性FDI对区域创新能力的提升有着显著的促进作用，且这种影响是非线性的；三种类型FDI都存在政府财政干预的单门槛效应，且当政府干预程度跨越门槛值，各类型FDI 对区域创新能力的提升作用越来越显著；在不同时间和空间因素下，异质性FDI对区域创新能力的影响不同。因此，可以通过调整各地区政府财政干预程度，平衡引资结构来促进区域创新能力的提升。

Government financial intervention,heterogeneous FDI and regional innovation capability

Regional innovation capability is an important factor to measure whether a region can achieve technological innovation, industrial transformation and upgrading, and economic growth. Foreign direct investment(FDI) is an important way for the host country to achieve regional innovation capabilities. The changes in international trade rules and the current changes in domestic economic environment have profoundly affected FDI investment form in China. Therefore, the reassessment of FDI investment motivation and its impact on regional innovation capabilities in various regions of our country has become a practical problem that domestic scholars and policy makers need to solve urgently at the theoretical and empirical levels. Based on the heterogeneity of FDI, this paper discusses the impact of FDI on regional innovation capabilities from the three types of resource-oriented FDI, efficiency-oriented FDI and market-oriented FDI. The results caused by regional innovation behaviors have the characteristics of public products such as uncertainty and externalities, which make innovation behaviors, have the possibility of market failure. This provides theoretical support for government intervention in innovation activities. Schumpeter, the founder of innovation theory, believes that technological innovation is high-input and high-risk. Only large enterprises with strong qualifications are able to bear the investment and risks of technological innovation, and it is difficult for small and medium-sized enterprises with weak strength to realize technological innovation. Therefore, in practice, the government needs to balance the interests between small and medium-sized enterprises in innovative activities so that the social economy can achieve healthy and sustainable growth. On this basis, this paper incorporates government fiscal intervention into the research framework of the impact of heterogeneous FDI on regional innovation capabilities, and studies the nonlinear threshold effect of government fiscal intervention. This paper divides China′s provinces into eastern and western regions to analyze regional differences in order to explain the impact of regional differences in heterogeneous FDI on regional innovation capabilities. Taking 2008 as the dividing line, further analyze the impact of heterogeneous FDI on regional innovation capabilities in different time periods.The conclusions show that:(1) Different types of FDI have a significant role in promoting regional innovation capabilities. However, after the combined effect, the impact of resource-oriented FDI on regional innovation capabilities has failed to pass the significance test. efficiency oriented FDI has a significant role in promoting regional innovation capability, and market-oriented FDI inhibits the improvement of regional innovation capabilities;(2) The impact of heterogeneous FDI on regional innovation capacity has threshold effect, that is, the impact of three different types of FDI on regional innovation ability has single threshold effect of government financial intervention, and with the strengthening of government intervention, all types of FDI have more and more significant effect on regional innovation ability;(3) The impact of heterogeneous FDI on regional innovation capabilities exists Certain regional differences. In the western region, the resource-based FDI has a significant promoting effect on the regional innovation capability, while the market-oriented FDI has no significant effect on the regional innovation capability;In the eastern region, the resource-based FDI has no significant effect on the regional innovation capability, and the market-oriented FDI has a significant promoting effect on the regional innovation capability;(4) There is a certain time difference in the influence of FDI on regional innovation capacity. Around 2008, different types of FDI have different impacts on regional innovation capability. Based on this, this article believes that it is possible to improve the regional innovation capabilities of various regions by adjusting the intensity of government financial intervention and balancing the investment structure.
